| 1 | Surface Activities of Calix [4]resorcinarenes Bearing Four Hydrophobic Chains and Its Solubilization for Organic Compounds显示文摘Calix resorcinarenes bearing four hydrophobic side chains ( Ar-Rn, Ar-Ph, and Ar-N) orient stably on water oil interface and show high solubilization capacities for organic compounds, such as long chain alcohols, benzene, toluene and dyes. The capacities are high even near the cmc of polyalkylated calix resorcinarenes, but the solubilities of organic compounds(solubilizates) decrease with the increase of the size of the solubilizates. Ar-R 6, with a chain length of six carbons, is the most effective among Ar-R n , Ar-Ph, and Ar-N; 11 fold mol of hexanol is dissolved in 2×10 -3 mol/L Ar-R 6. Moreover, Ar-R n bearing four alkyl side chains solubilizes the chain alcohols of the same chain length mostly. The solubilization capacities are presumably brought by inclusion in a large cavity of the polyalkylated calix resorcinarenes and by an efficient orientation of the solubilizates. | LI Bo *1 , Yoshifumi KOIDE 1 and Kunio ESUMI 21.
